jquery - How do I changes this code to make images rotate on refresh? -

-

I have recently asked how to rotate the images on an element and presented with this code - Which works perfectly: 

  counter = 1; Num_images = 9; Dir = "Image Director URL"; Function rotate image () {var background_img = 'url (' + dir + '/ image' + counter + '. Gif)'; JQuery ('# fader.category'). Fade (function () {jQuery ('# fader.category'). CSS ('background-image', background_image). FadeIn ('slow');}); Counter ++; If (counter> number_image) counter = 1; } Set intern ("rotate image ()", 25000);

My question is now: How can I customize this code to change images when I refresh a page? I am new to jQuery and Javascript in general so if someone provides a solution, please tell how this works, so I can learn and hopefully ask fewer questions later ... Thanks a lot. .

I use a random initial image to give you the illusion of change on every page load / refresh I recommend to do Otherwise you are left with writing a cookie of the last seen image and showing the next one on the page load:

Change the following two lines as follows (notice I reverse their purpose ): 

  number_imaj = 9; // Choose a random initial number counter = mathematics. Syll (mathematics.rendum) * num_images);

Of course there is a possibility of the same image that is randomly appearing again in a row, but it will probably be very close to your will.

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
